The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a 
400 MHz pixel clock to the PCI Express x16 connector.  When an ADD2/MEC/ADD2+ 
card is detected, the Intel GMA X4500HD graphics controller is enabled and the PCI 
Express x16 connector is configured for SDVO mode.  SDVO mode enables the SDVO 
ports to be accessed by the ADD2/MEC/ADD2+ card.  An ADD2/MEC/ADD2+ card can 
either be configured to support simultaneous display or can be configured to support 
dual independent display as an extended desktop configuration with different color 
depths and resolutions with DVI analog output only.  ADD2/MEC/ADD2+ cards can be 
designed to support the following configurations: 
•  Low Voltage Differential Signaling (LVDS) 
•  Single device operating in dual channel mode 
•  HDTV output 

The GMCH also supports add in discrete graphics card via the PCI Express 2.0 graphics 
connector. 
•  PCI Express 2.0 x16:   

⎯  Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each 

direction (500 MB/s total). Maximum theoretical bandwidth on interface of 
4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when 
operating in x16 mode. 

⎯  Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each 

direction (1000 MB/s total). Maximum theoretical bandwidth on interface of 
8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when 
operating in x16 mode. 

 

 

PCI Express technology 

The board supports up to twelve USB 2.0 ports, supports UHCI and EHCI, and uses 
UHCI- and EHCI-compatible drivers.   

The Intel ICH10 provides the USB controller for all ports.  The port arrangement is as 
follows: 
•  Six ports are implemented with stacked back panel connectors 
•  Six ports are routed to three separate front panel USB headers
